MECHANICAL MOVEMENT.

Specification of Letters Patent. Patented J une 29, 1920.

Application filed July 22, 1919. Serial No. 312,644.

To all whom it may concern:

Be it known that I, DANIEL H. SMITH, a citizen of the United States, residing at Shirley, in the county of Van Buren and State of Arkansas, have invented certain new and useful Improvements in Mechanical Movements, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in mechanical movements, and it is an object of the invention to provide a novel and improved device of this general character whereby oscillatory movement is converted into rotary movement.

Another object of the invention is to provide a novel and improved device of this general character including a frame mounted for oscillation and which frame moves about a substantially horizontal axis and in which frame is mounted for rotation about a vertically disposed axis a rotary member hav ing a peripheral portion weighted so that such rotary member is caused to continuously revolve upon proper oscillation of the frame.

An additional object of the invention is to provide a novel and improved device of this general character including a swinging or oscillating frame and a rotatable member carried thereby and wherein the axes of the frame and rotatable member are substantially perpendicularly related, a

peripheral portion of the rotatable member being weighted whereby the rotatable member is caused to revolve by gravity upon proper oscillation of the frame.

Furthermore, it is an object of the invention to provide a novel and improved device of this general character including an oscillating frame and a rotatable member carried thereby and caused to revolve by gravity upon proper oscillation of the frame, together with means to prevent a dead center of the rotatable member.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved mechanicalmovement whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advanta eous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 isa view in side elevation with portions in section of a mechanical movement constructed in accordance with an em bodiment of my invention.

Flg. 2 is a view in top plan with portions in section of the device as illustrated in Fig. 1.

Fig. 3 is a view partly in vertical section and partly in elevation taken through an end portion of the device as illustrated in F 1g. 1 and wherein the operative connection between the pendulum and oscillating frame is illustrated in detail.

Fig. 4 is a fragmentary view taken through a peripheral portion of the rotatable member carried by the oscillating frame and showing a means for weighting the peripheral portion of said member.

Fig. 5 is a fragmentary view partly in section and partly in elevation of the lower or weighted end portion of the pendulum.

As disclosed in the accompanying drawings, B denotes a base or platform positioned at a desired altitude and herein disclosed as supported through the instrumentality of the legs 1. The base or platform B is provided with a pair of upstanding and longitudinally spaced and alined posts or plates 2 between which is mounted for swinging or oscillating movement the frame F.

The frame F is preferably oblong in form with its longitudinal axis horizontally disposed and the central portions of the end members 3 of said frame F are provided with trunnions 4 indicated by dotted lines in Fig. 1 and which trunnions are suitably engaged with the posts or plates 2.

The side'members 5 of the frame F at substantially their longitudinal centers are provided with the bearings 6 alined transversely of the frame F and with which are rotatably engaged the opposite end portions of a shaft 7 whereby said shaft 7 is perpendicularly related to the axis of oscillation of the frame F.

Keyed or otherwise secured to the shaft 7 is a wheel WV of a diameter slightly less than the interior longitudinal diameter of the frame F. However, I wish to state at this time that I do not wish to be understood as limiting myself to this exact diameter as the diameter of the wheel V will be controlled by the requirements or necessities of practice.

The peripheral marginal portion of the wheel lV'has extending circumferentially of the wheel but of a length less than onequarter of the circumference an arcuate series of pockets or compartments 8 adapted to be closed by a cover or li( 9 herein disclosed as common to all of the pockets or compartments 8. Arranged within the pockets or compartments 8 is a suitable weighted mass 10; This mass may be of any desired material but prefeably granular so that the desired weight at a side or peripheral portion of the wheel 1V may be readily and conveniently regulated to best meet the requirements of practice.

By having a marginal or peripheral por-- tion of the wheel W weighted it will be understood that upon swin ing of the frame F in a direction away rrom the particular location of the weighted side of the wheel, said wheel IV will rotate by gravity and by properly oscillating the frame F the rotation of the wheel 1V may be made continuous and the speed of rotation substantially regulated to best meet conditions.

In order to limit the extent of oscillation of the frame F I find it of advantage to provide one of the posts or plates 2 with the inwardly extending lugs or arms 11 and between which an end portion of the frame F is arranged. The opposed faces of the lugs or arms 11 are provided with the inwardly directed expansible and yieldable members 12 herein disclosed as coiled springs. The members 12 operate to facilitate the requisite oscillation of the frame F during a working operation.

The frame is adapted to be manually operated and for which reason the upper side member 5 of the frame F is provided with an upstanding handle or lever member 1 1 which is adapted to be grasped by the oper ator to positively rock or oscillate the frame F to assure the desired continuous rotation of the wheel IV.

lVhile generally the momentum of the wheel IV will prevent a dead center, I find it of advantage to'provide means to further assure this objection and as herein disclosed I employ a pendulum I which is vertically disposed and pivotally supported intermediate its length as at 15 between the brackets 16 depending from the base or platform B at opposite sides of a slot or opening 17 formed in the base or platform B. The upper end. portion of the pendulum extends through the opening or slot 17 and said upper end portion is provided with an open slot or kerf 18 which has disposed therethrough a pin or cross member 19. The pin or cross member 19 is herein disclosed as engaged with the depending ears 20 carried by the lower side member 5 of the frame F.

The weighted member M arranged at the lower end portion of the pendulum P is herein disclosed as comprising a hollow body closed at its lower end and in which is adapted to be deposited suitable weighting material 21. lVhile this material 21 may be of any character desired it is also preferred that it he granular so that the weight of the member M may be conveniently regulated as preferred.

The operative connection between the frame F and the pendulum P is such that when the frame F swings in one direction the lower or weighted end of the pendulum I" will swing in an opposite direction. By this means the desired oscillation of the frame G is assured and particularly in the event the operator should fail to manually impart the requisite movement to such frame. With the oscillation of the frame F assured the possibility of the wheel W reaching a dead center is substantially entirely eliminated.

The shaft '7 has also suitably engaged therewith a pulley 22 or other driving memher which is adapted to be placed in suitable connection with a driven member generally indicated as 23.

From the foregoing description, it is thought to be obvious that a mechanical movement constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
